A
-A region in space where a charged object experiences an electrostatic force
2
Q
How are positive objects charged
A
-They lost electrons
3
Q
How are negative objects charged
A
-They gain electrons
4
Q
What is polarization
A
-Explains how charged objects attract neutral objects
-it is the shift of negative and positive charges within an object which results in 2 dipoles being formed
-Objects still remain neutral because electrons aren’t lost they are just shifted
5
Q
Why can only insulators be charged by friction
A
-Electrons transfer from one object to another through friction
